double midget penetration
sliding a midget onto a sufficiently large penis so that it is able to travel through one whole and out of the other, push the midget down and make love to another midget with the remainder of the penis.
Things got out of hand last night and i ended up commiting an act of double midget penetration with Ivy and Dot, you know, the two old ladies from across the street, boy do i regret it now...
